Magnetism and Electricity Flashcards
Energy
Motion or interaction of molecules, the ability to do work.
Electron
Subatomic particle that has a negative charge.
Magnetism
A force that can attract or repel objects that contain a magnetic material inside them
-cause by electrical charges
-magnetic materials: cobalt, nickel, iron, magnetite.
Magnetic Field
A region around a magnetic material where the force of magnetism acts
*flow from positive to negative.
Charge
A physical property that causes matter to experience a force.
-Protons are positively charged
-Electrons are negatively charged
Attract
Being drawn to another object
*Opposite charges attract
Repel
To push away from something
*Same charges repel
Electricity
Energy resulting from charged particles.
Static Electricicty
An imbalance of electric charges within a material.
Electric Field
The area around an electric charge experiences an electric force.
*Flow from positive to negative
Electric Current
When electric charges move.
Open Circuit
A path that electricity flows along that is interrupted or disconnected.
Closed Circuit
A complete path of electrical connection around which a current flows or circulates.
Series Circuit
One path through which electricity flows.
Parallel Circuit
Multiple paths for electricity to flow from one point to another.
